Now work really fine! thank u so much Priyanka !!!!!!
my problem was that the date selector kept appearing, but in the end what I did is that I send the date from the form with get and I show all the data in a second web.

I try again…

It does not work for me.
The purpose of the web is to select a date in a form, and in that same web, to show the queries that are made to the database and that canvasjs draw the graph with the sales data.

I check that the data enters the array:

array in json with numeric check:
[{“label”:”TPV 1″,”y”:2},{“label”:”TPV 2″,”y”:2},{“label”:”TPV 3″,”y”:2},{“label”:”TPV 4″,”y”:482}]

which I do not know why canvasjs does not draw it :(

—-
I think canvasjs has no data because it runs in head.
– first: canvas draws the graph (but no have data).
– second: I request the date in the form.
– third: I make operations with data, variables, I draw the html table …
– 4: in the end, I call the chartcontainer, but this has no information, because it has not returned to the head.

[tekit0]

Can the problem of how do I get the variable come?

$f_1 = mysqli_fetch_row($result_f1)

and then I echo the variable $f_1[0]

[tekit0]

I try this example : https://canvasjs.com/php-charts/chart-index-data-label/

but is similar, don’t draw the data.
I use xampp and i have enable the json
json version 1.6.0
